We’re delighted to announce that Mattermost 3.5 is now available for download. It increases system performance, especially at scale. It’s also easier to install and there are significant enhancements for mobile apps. Plus, we are pleased to welcome Russian speakers to Mattermost, which is now available in 11 languages. Thanks to all who have contributed and in particular our Most Valuable Professional for Mattermost 3.5, Harshavardhana who added Minio support for Mattermost file storage.

New mobile experience offers larger, easier-to-tap menu buttons. BEFORE on left, and AFTER on right.

Minio as Self-Hosted S3-Alternative to Local File Storage

It is lightweight and easy to set up in a few minutes. The Amazon S3 compatible API enables users to adopt any cloud environment, both on-premise and hosted. Minio even has advanced features like erasure code, bitrot and lambda notifications.

Russian Language Translation

Russian is our 11th language for Mattermost, expanding our software to another 150-250 million speakers.

This is one of the final major languages to arrive in Mattermost and we’re excited to be completing the set. Workplace messaging with Mattermost is available in English, German, French, Spanish, Chinese, Korean, Japanese, Dutch, Portuguese and now Russian.

Thanks to the dozens of contributors who helped make the Russian release possible:

Standalone Web Server Mode

Mattermost 3.5 removes NGINX dependency with a “standalone web server” mode with auto-configuration of certificates via Let’s Encrypt. It gets us closer to making an Ubuntu/Debian package with seamless support for sudo apt-get install mattermost.

Improved Slack Import

Need to import from Slack? Then you’ll find several improvements in the new release, including support for:

Duplicate users

Slack channel topic and purpose

Comments on file uploads

Join/leave messages

Bot and integration messages

Channel linking

/me messages

Moreover, a new CLI command, slack_import, supports the import of a Slack export zip archive file.

Huge thanks to George Goldberg for working on many of these improvements! George did such fantastic job we offered him a permanent role as a core committer and he’ll be joining Mattermost, Inc. full time. If you’re a contributor interested in a new career in open source, please let us know!
